Building the future
Construction
• Better corporation: Lean Construction and partnering
• Key figures - benchmark
• Digital construction

Building the future
• A contractor must present a ”mark book” before being allowed to work for the Danish State and other public authorities.
• The ”mark book” contains key figures on time, quality safety and customers satisfaction collected during the latest years

Building the future
Materials and components
• Self compacting concrete SCC
• Ready built Penthouses
• Masonry- versus timber houses
![Page 17: Building the future Bjørn Lykke Jensen Director, Building technology Danish Technological Institute NEW DEVELOPMENTS IN THE DANISH BUILDING SECTOR](https://reader035.vdocuments.site/reader035/viewer/2022062409/56649f215503460f94c39d96/html5/thumbnails/17.jpg)
Building the future
Self-compacting concrete
Features:increased productivity, reduced environmental impacts (no vibration and noise), improved concrete quality (no vibration to damage the air void structure) and fewer defects in casting difficult details and dense reinforcement.
But requires:Better control of the materials, better casting logistics, better control of pressure on formwork and on incomplete compacting

Building the future
A future building combining the human needs for good indoor comfort, low energy consumption and use of renewable energy
The prototype was manufactured in an industrial process and transported to the site for mounting
SOLTAG – A prototype of a CO2 neutral apartment
![Page 19: Building the future Bjørn Lykke Jensen Director, Building technology Danish Technological Institute NEW DEVELOPMENTS IN THE DANISH BUILDING SECTOR](https://reader035.vdocuments.site/reader035/viewer/2022062409/56649f215503460f94c39d96/html5/thumbnails/19.jpg)
Building the future
The prototype combine the basic human needs for fresh air, daylight and good comfort with the general need for low energy consumption

Building the future
In Copenhagen there are among 100.000 m2 with flat roof, that can be used for roof apartments.
The area is assumed to be much bigger in the central and eastern Europe.

Building the future
Masonry vs. timber
Competition through
1. Indoor climate2. Price and time3. ”the feeling” (heavy vs. Light)4. Durability and maintenance
